摘要: Summary Effects of reticuloendotheliosis virus (REV) on the response to infectious laryngotracheitis (ILTV) were investigated in young chickens with and without maternally derived antibody (MAb) REV. In first experiment a group 1‐day‐old REV MAb inoculated at 1 day age whilst another similar left uninoculated. All vaccinated ILTV 7 days age. There was significantly higher proportion (ILT) post‐vaccinal ophthalmia (p.v.o.) second old These chickens, together others not REV, isolate SA‐2 8 later. A virulent isolate, G, used challenge all 20 after vaccination. Again showed ILT p.v.o. significantly...
